I have a 2007 jeep wrangler X, I've put a 2" suspension lift by rough country on there 3 months ago, and now my ABS, TCS, ESP, BAS lights are on, I did have the recall sent to me about the traction control. the day I took it in for that was when the lights had just came on, I told them that the lights had come on. then they drove it around and the guy came up to me and said do you have suspension work done I was like yeah, he was like well the lights are on b. c you stretched the brake lines and the ABS wire was stretched or you pinched it, I have not taken it off-roading sense I put the lift on there so I have not been able to flex the suspension to have stretched the wires out, and that I had voided my warranty and they were going to charge me $106 an hour to look at it and if they found out it was a problem with the computer they would fix it under warranty, but if not I had to pay for it, I have checked the wires and the fuses, and I even did the test with the ignition to see if there are any trouble codes stored in the computer, and I had none and I do not know what to do about it.
Other than that I have had a blast in the jeep,
i like the 3 piece hard top,
yes taking it off is a pain, but its not that bad,
i have more room in this one than I did with my first jeep wrangler 1994,
the sound system is not bad, but nothing great.
I like the handling on the jeep
the engine and trans could have been different instead of a mini van.
Typical dealership... they have stupid mechanics and if they can't figure out what is wrong right away, then they try to blame it on you. Under Federal Law THEY have to PROVE that your suspension work caused the problem.. NOT the other way around.
Just because you haven't taken it off roading since you installed the suspension lift doesn't mean you didn't stretch the brake hose from the lift itself. If you didn't install longer brake hoses at the time you did the lift, you probably did stretch the hose.
